全球大气二氧化碳(CO2)浓度不断升高对农业生产带来巨大影响。二氧化碳是作物光合作用的底物, 其浓度的升高理论上有利于作物光合作用能力的提高, 从而促进作物生物量和产量的形成。但已有研究表明, 大气CO2浓度升高对作物产量的促进作用小于预期, 同时还存在使作物营养品质变劣的风险, 相关机制尚不清楚。为此, 本文从植物...
The higher the Zonyl-TM content used in the feed, the higher the J crit time and the lower the weight-average molecular weight (M w) of the copolymer obtained. Thermal analysis results of the copolymer indicated that the copolymers are stable up to 387–403 °C. 展开 关键词: Perfluoro...
It was calculated using the following equation: \({\text{R}}_{{{\text{CO}}_{{\text{2}}} }}\) = CCP(\({\text{M}}_{{{\text{CO}}_{{\text{2}}} }}\)/Mc), where P is the biomass productivity (g L−1 day−1), MC is the molecular weight of carbon, and \({\...
Further constraints on the origins and processes affecting these gases are provided by the molecular-average and clumped isotope compositions of the associated CH4. We observe a relatively high δ13C of CO2(13.6 ± 3.2‰) and CH4(−47.7 ± 1.7‰) at Olla compared with those obs...
Eventually, the training stage of every regression tree can be indicated as\({W}_{q(x)} , q \in \left\{\text{1,2},3,\dots ,N\right\}\); whereWdenotes a weight term of every leaf node,qshows utilized decision rules in each tree, andNindicates the number of leaves in a tree...
